p*1=c that is p=c hence the process is at constant pressure process.

We know "v" to the power 0 is 1 so we get p = const.

Sharad Ingle said: (Sep 23, 2013)  
When V=1 then P*1=C.

And 0 power of anything=1.

We know anything raise to 0 is 1 so v=1 and p*1=c i.e. p=c therefore constant pressure process.

G Sudhakarreddy said: (Aug 23, 2014)  
When n=0, the equation may write as p=c.
So pressure is constant.

Its wrong, this is according to thermodynamics second law and einstein 2nd law.

Isothermal process pv = c.

Madai Nayagan said: (Nov 29, 2016)  
If anything to the power zero is value zero V power 0 is zero so P is equal to c (constant).

If n=0 then p=C hence we can say that pressure constant process.

PVn = C polytropic process.
PV = C isothermal process.

If n=1 what will happen?

Narsingh said: (Oct 10, 2017)  
n=0,pv^0=constant.i .e.,isobaric process (p=const).
n=1,pv=const.i.e., Isothermal process (temperature= const).
n=gama,pv^gama=const.i.e., Isentropic process.
n=infinity,pv^infinity=consnt.i.e.,v= const i.e, isochoric process (v= const).

Paul said: (Aug 12, 2018)  
It should be isothermal process.

Ausha.Ambati said: (Feb 10, 2019)  
When n is 0 in this equation then P is constant.

Monika Jondani said: (Apr 17, 2019)  
n=0 Isobaric.
n=1. Isothermal.
n>1. Polytropic.
n=gamm. Adiabatic.
n=infitniy Constant volume.

Yash said: (Jul 2, 2019)  
There are three basic processes:

1. pv^n = c is polytropic process.
2. pv^gamma=c is an adiabatic process.
3. pv=c is isothermal process.
